A problem with the rotation of objects in c#

Question

using System.Collections.Generic;
using UnityEngine;

public class RotationPlasmaCast : MonoBehaviour
{
    float LockPos = 0;
    public Transform Squid;
    float SquidRot = Squid.z;

    void FixedUpdate()
    {
        transform.rotation = Quaternion.Euler(LockPos, LockPos, SquidRot.rotation);
    }
}

I used this code to make the rotation of my projectile (PlasmaCast) the same as my player (Squid). Unity tells me:

A field initializer cannot reference the non-static field, method, or property 'RotationPlasmaCast.Squid

Does anyone know why Unity gives me an error?

Answer 1

Assuming you want to store the Squid's Z rotation for use elsewhere in your code, you would set your initial rotation to 0 and during your FixedUpdate() function you would update that value to match its current rotation and pass that into your transform like so:

using System.Collections.Generic;
using UnityEngine;

public class RotationPlasmaCast : MonoBehaviour
{
    float LockPos = 0;
    public Transform Squid;
    float SquidRot = 0;

    void FixedUpdate()
    {
        SquidRot = Squid.rotation.z;
        transform.rotation = Quaternion.Euler(LockPos, LockPos, SquidRot);
    }
}

Its worth noting that depending on the heirarchy of your GameObjects you may need to use 'localRotation' instead of 'rotation'
